细胞周期蛋白依赖性激酶(CDKs)在一系列重要的细胞过程中起着至关重要的作用。虽然经典的两步激活机制通常适用于细胞周期相关的CDK,但参与转录调控的CDK 7和CDK 8均采用不同的激酶激活机制。在这两种情况下,与各自的细胞周期蛋白伴侣结合仅导致部分活性,而它们的完全激活需要额外的亚基的存在。最近对这两种非经典激酶的结构研究为其激活机制提供了前所未有的见解,使我们能够了解第三亚基如何协调T环稳定并增强激酶活性。在这篇综述中,我们总结了CDK7和CDK8各自的功能复合物的结构和功能,同时也描述了它们的非经典激活机制。这些见解为靶向药物发现和与CDK7和CDK8相关的各种疾病的潜在治疗干预开辟了新途径。
The Cyclin-dependent kinases (CDKs) play crucial roles in a range of essential cellular processes. While the classical two-step activation mechanism is generally applicable to cell cycle-related CDKs, both CDK7 and CDK8, involved in transcriptional regulation, adopt distinct mechanisms for kinase activation. In both cases, binding to their respective cyclin partners results in only partial activity, while their full activation requires the presence of an additional subunit. Recent structural studies of these two noncanonical kinases have provided unprecedented insights into their activation mechanisms, enabling us to understand how the third subunit coordinates the T-loop stabilization and enhances kinase activity. In this review, we summarize the structure and function of CDK7 and CDK8 within their respective functional complexes, while also describing their noncanonical activation mechanisms. These insights open new avenues for targeted drug discovery and potential therapeutic interventions in various diseases related to CDK7 and CDK8.
